Linda Sue Park is the author of The 39 Clues Book 9: Storm Warning, and Cahills vs Vespers Book 5: Trust No One. She appeared on the Message Board very recently to announce the release of Trust No One in a post titled: Book 5: TRUST NO ONE--Available NOW!

She is also famous for putting minor swear words in her novel, Trust No One. This caused major controversy on the Message Board, agents disagreeing with the swearing threatening to stop reading or force the authors to sign a petition agreeing that no swear words (including the use of "god" in "oh my god") should be included. So far, she nor the mods have responded.
